From the Highway start heading straight up the main USFS road (62, I believe). It is a steep 2.7 miles to the summit of Currahee mountain, and the road is often washed out, wash boarded, and rutted. It gets maintained regularly, but can degrade quickly. Elevation at the beginning of the road is 1201'. Elevation at the top of Currahee: 1719'. But it isn't a straight climb to the top, there are several serious downhills on the way up that make you curse the people who built that road, but it is definitely a serious workout. If you are really masochistic, start at the gas station on 17 (elev. 814') and add those 5 miles of paved hill on top of it. But when you do get to the top, you are rewarded with one of the best views in Northeast Georgia!
